Abstract: Under the background of regional interaction in East Asia, the change of bilateral relations between South Korea and Japan has promoted the transformation of Japanese majors in South Korean universities. The study found that the transformation of Korean Japanese major is not only due to the internal needs of its education system, but also an institutional response to the impact of South Korea-Japan relations. The interactive mechanism of economy, trade and culture, the transmission mechanism of system and the individual selection mechanism of learners jointly promote the transformation of the training objectives of Korean Japanese major from single language ability to compound ability, and promote the interdisciplinary integration and functional differentiation of Japanese related majors. At the same time, demographic changes, higher education reform and artificial intelligence technology have further accelerated this transformation process. Although the employment adaptability has been improved after the transformation, Japanese majors in South Korean universities still need to cope with the challenges such as the conflict between humanity and application, the contraction of students and the lag of curriculum and post demand. From a regional and national perspective, bilateral relations, as an intermediary mechanism, are reshaping the organizational system and talent training structure of Japanese-related majors in universities in Japans neighboring countries.
